In the crystal of the title compound, [Cd2Na2(C2H3O2)2(C21H24N2O4)2]·0.67C2H6O, the doubly deprotonated Schiff base ligand N,N′,O,O′-chelates to the CdII cation, which is also O,O′-chelated by the acetate ion. Two Cd–Schiff base units are connected to two Na+ atoms to form the tetranuclear complex, in which the Cd2+ and Na+ cations show distorted octahedral coordinations. The asymmetric unit consists of half a tetranuclear molecule (lying on an inversion center) and a full tetranuclear molecule (lying on a general position) along with a lattice ethanol molecule, which links to the coordinating acetate ion via an O—H...O hydrogen bond. In the crystal, the propyl and ethyl groups of the complex molecule are disordered over two positions in a 1:1 ratio; the ethyl group of the lattice ethanol molecule is also equally disordered over two positions.
